Did you have to worry about the SPI clock mode and set it differently then default?

According to the ongoing thread at RaspberryPi.org, there may be issues with the [SPI clock rate](http://www.raspberrypi.org/phpBB3/viewtopic.php?f=32&amp;amp;t=9814&amp;amp;hilit=nokia&amp;amp;sid=ed791e24f3284358d0c945adef543591&amp;amp;start=125#p264832 &quot;SPI clock rate&quot;) with some combinations of LCD and Raspberry Pi hardware revisions.http://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83k0w0AntiMe on I made this: qrclock, an SPI-driven LCD pointless thinghttp://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83k0w02013-01-25T12:41:50.353970-08:00All the code is in the article, quite prominently.http://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83k7ta[deleted] on I made this: qrclock, an SPI-driven LCD pointless thinghttp://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83k7ta2013-01-25T12:50:54.535702-08:00Sorry I should have RTFA.http://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83m6r2LightWolfCavalry on I made this: qrclock, an SPI-driven LCD pointless thinghttp://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83m6r22013-01-25T14:26:40.569778-08:00There's a QR code python library?

The [mozillazg/python-qrcode](https://github.com/mozillazg/python-qrcode) fork doesn't provide all of the text encoding magic that I'd want, but I'd rather swap that for the ability to use most of the PIL functions on the result.http://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83paqgLightWolfCavalry on I made this: qrclock, an SPI-driven LCD pointless thinghttp://www.reddit.com/r/raspberry_pi/comments/179174/i_made_this_qrclock_an_spidriven_lcd_pointless/c83paqg2013-01-25T17:21:48.817966-08:00Cool!
